Shingle-machine



UNITED STATES ROBERT L. NOBLET, OF HAVERFORD, PENNSYLVANIA.

SHIN GLE-MACHINE.

Specification of Letters Patent No. 9,118, dated July 13, 1852.

To all whom tt may concern:

Be it known that I, ROBERT L. NoBLn'r, of Haverford, in the county of Delaware and State of Pennsylvania, have invented certain new and useful Improvements in ShingleWIaehines; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part thereof, in which- Figure l, represents a view from the front of the machine. Fig. 2, represents a view from one of the ends. Fig. 3, represents a top view, and Fig. el., a vertical section through the red line fr, m, of Fig. 8.

Similar letters in the several figures representthe same parts,

The nature of my invention consists in making the double racks, which regulate the feeding up of the carriage carrying the bolt, from which the shingles are to be cut, in segments, one of which may be stationary, and the other adjustable, so as to adapt the machine to the cutting of shingles of various thicknesses at the butt and point wit-h the same racks. And also in supporting and moving the carriage, on a slotted bar placed under the center thereof, by means of the slot in said bar, and the guide on the carriage which moves in it, for the double purpose of allowing the carriage to vibrate on its center, as it feeds up the bolt to the knife, so as to have the butts and points of the shingles out alternately from the same ends of the bolts, and to prevent any endwise motion of the carriage.

To enable others skilled in the art to make and use my invention, I will proceed to describe the same with reference to the drawin s.

gA, represents the top of the bench or table, with grooved guides B, on each end thereof, 0n which bench, and between which grooves the carriage C slides.

D, is the head block, to which the bolt, from which the shingles are to be cut, is fastened by dogs in any of the well known ways. Underneath the center of the carriage, and at right angles thereto is framed a fixed slotted bar E, having a longitudinal slot F, cut therein, in which slot moves a guide a, attached to the undersideof the carriage by a pin, bolt, or otherwise, and which is rounded off on the sides, so that they shall only touch the sides of the slot at a point, and so that the carriage may vibrate from that point as a center, for the purpose of bringing up the bolt to the knife in such manner as to have the butts and points of the shingles cut alternately from the same ends Vof the bolt.

The knife frame G, works obliquely, in inclined ways H, and the knife l, is set therein, so as to form an acute angle with the bench-this gives the knife a draw cut through the bolt. To the knife frame is attached a rod b, by one of its ends-the other end of said rod being fastened to one end of the lever J, which is hung to the frame. On the other end of the lever J, is hinged an arm K, which operates a pawl L, working into a ratchet M, to be presently described. The pawl L, is held up to the ratchet by a spring c.

In suitable bearings ll, on the side of the frame, near the top of the bench, is arranged a cam wheel O, to which the ratchet M is attached. The ratchet receives its motion from the knife frame by means of the rod, lever, arm and pawl before described and communicates motion to the cam wheel to which it is attached. The cams are formed o-n the periphery of the cam wheel, and above and extending clear across the bench is placed a vibrating bar P, moving in guides Q, said bar having in its end over the cam wheel two pins e, between which the cams rotate and give to said bar its vi bratory motion.

Parallel with the slotted bar E, and about midway between it and each of the ends of the bench, are placed the double racks R, made in sections, one of which sections may be permanent-ly attached to the bench, and the other adjustable by means of a slot cl, and set screw f, so that by shifting one of the segments the taper of the shingle may be varied at pleasure. If found essential, both of the segments may be made adjustable, but in practice the adjustability of one has been found sufficient.

On the vibrating bar P, are two horizontal arms g, which should be long enough to operate the spring dogs 7L, which are attached to, and move up with, the carriage, until the bolt is entirely cut up-said arms passing into mortises between the carriage and head block, in which they may move loosely. The spring dogs 7L, are arranged underneath the carriage, so as to play into the double racks R, and attached to them, are the arms z', which pass up through the carriage on each side of the arms g, of the vibrating bar, so that as said bar vibrates by the operation of the cam wheel, it will throw back one set of Vspring dogs (of which there are double sets), and the other set being released move by the action of the Y springjinto the rack, and catch and hold the carriage, which is drawn forward when released by the dogs, by the weights S, attached to it. By having the teeth inthe racks, not directly opposite each other, it will be perceived that the carriage is fed up with a kind of regular swinging motion, which brings up the bolt properly for having the butts and points out alternately from the same ends of the bolt.

Underneath the machine are arranged two shafts T, meet-ing in a boss or sleeve U, in the center of the machine, so that they may be moved independently of each other, and to the extreme ends of said shafts, are arranged handles V, which extend up along side of the table, and in convenient position for the operato-r. To these shafts are irmly fixed the arms Z, which are connected to the carriage by straps f. `The object of this arrangement is to allow the operator, when the bolt is knotty, cross grained or of very hard wood, by catching hold of the handles, to hold the carriage from being jumped back, when the knife strikes against such hard bolt. These handles may be operated by springs or weights if deemed essential.

To one of the bottom pieces of the frame is hinged a piece W, which has two jointed or hinged arms Y, on its upper end which arms when raised up (they are represented in the drawings as being folded down) project above the bench. To this piece lV, is aiiiXed a treadle X, in convenient position for the operator, and is intended for carrying up the shingles when cnt, to be jointedthe shingles being placed in faggots on the bench, and the foot applied to .the treadle, forces them forward under the knife until their edges are all dressed, when by removing the foot, the spring m, forces back the piece W, and the shingles are removed.

The machine may be driven by horse, water, steam or any other kind of power.

Having thus fully described my invention, what I claim therein as new and desire to secure by Letters Patent -is- Making the double racks in segments-one of which is stationary, and the other adjustable, for the purpose of cutting shingles of various thicknesses at butt and point with the same racks, substantially as described.
